NAIROBI: At least four people died when a cargo plane crashed into a building shortly after takeoff on Wednesday from the Kenyan capital’s main airport, the busiest in east Africa, aviation authorities said. “A Fokker 50 cargo plane with four people on board has this morning crashed at a commercial building,” after taking off from Nairobi’s Jomo Kenyatta International Airport (JKIA), Kenya Airports authority said in a statement. The plane crashed before dawn on Wednesday, a time when the building would be expected to be largely empty. An Agence France-Presse photographer at the scene said the plane had smashed into a low-rise building containing small stores and shops, some three kilometers (two miles) from the airport. Police sources said all four people on the plane were dead.
